Enable SSID broadcast keeps turning on after device restart

Hi, i have a second wireless network for IOT device and want this SSID hidden.

I turn off enable SSID broadcast and works fine, but if the device is restarted then the enable SSID broadcast is ticked again and the SSID is no longer hidden.

How can this setting stay after the device is restarted after i have turned it off?

SXR80 / SXS80

Firmware Version
V4.2.3.102

Thanks
